Channels transport messages across remoting boundaries (for example, between computers or application domains). The HttpClientChannel class transports messages using the HTTP protocol.

Channels are used by the .NET Framework remoting infrastructure to transport remote calls. When a client makes a call to a remote object, the call is serialized into a message that is sent by a client channel and received by a server channel. It is then deserialized and processed. Any returned values are transmitted by the server channel and received by the client channel.

To perform additional processing of messages on the client-side, you can specify an implementation of the IClientChannelSinkProvider through which all messages processed by the HttpClientChannel are passed.

By default, the HttpServerChannel uses a SOAP formatter to serialize all messages.

A HttpClientChannel object has associated configuration properties that can be set at run time either in a configuration file (by invoking the static RemotingConfiguration.Configure method) or programmatically (by passing a IDictionary collection to the HttpClientChannel constructor). For a list of these configuration properties, see Channel and Formatter Configuration Properties.

The following code example shows how to use a HttpClientChannel to set up a remoting server and its client. The example contains three parts:

  • A server

  • A client

  • A remote object used by the server and the client

The following code example shows a server.
